Abstract
Various embodiments include a circuit arrangement comprising: a heat sink; and a set of layers arranged on a surface of the heat sink. The set of layers includes a first electrically insulating insulation layer and an electrically conductive conductor layer arranged on a side of the insulation layer facing away from the heat sink. The set of layers includes an electrical connecting path between two electrical connection regions. At least one layer of the set of layers is formed by cold gas spraying of a respective material.
